PUMP.

Specification of Letters Patent.

Patented Get. 21, 1913.

Application filed February 8, 1912. Serial No. 676,238.

To all whom Z5 may concern.'

Be it known that I, HARRY MEAD, a citi-l zen of the United States, and a resident of Coalinga, in the county of Fresno and State of California, have invente-d a new and Improved Pump, of which the following is a full, clear, and exact description.

My invention relates to pumps, and especially to oil pumps, and it has for its object to provide one which will hold in suspension uniformly, from the bottom to the top of the well, the sand which becomes mixed with the oil or substance which is being pumped. My improvement will prevent the sand from settling back and sanding up the pump, and

it will therefore do away with the necessity of frequently cleaning out the pumps, or

making repairs such as the substitution of plungers in place of those which have been worn by the sand.

`W ith the pumps now in use there is a heavy pressure exerted on the pump by the column of oil above the pump. This is especially soin deep wells, and the result is what are known as blow-outs; that is, the pump is so damaged that it will no longer produce the necessary vacuum on the stroke of the pump. This danger is also overcome with my improvement.

My improvement, which is secured to the sucker rod, consists of a plurality of lifting wings which extend radially, and overlap each other, each of the lifting wings having one of its sides beveled at the bottom -for engaging the side of an adjacent liftingwing, beveled at the top.

Additional objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed.

ln the drawings, similar characters of reference indicate corresponding parts in all the views, in which- Figure 1 is a sectional view of a well casing with a sucker rod provided with my improvement; Fig. 2 is an enlarged view, partially in section, showing the device as secured to the sucker rod; Fig. 3 is a plan view of Fig. 2, partially in section; Fig. 4 is an end view of one of the lifting wings; and Fig. 5 is a plan view of one of the lifting winOs.

By referring to the drawings it will e seen that in the well casing 5 there is disposed a sucker rod 6, for operating a pump of the usual type and this sucker rod is constructed of sections 7, which are connected together by the members 8. l prefer to construct these members 8 with an outer thread 9, at one end, and an inner thread 10 at the other end, by which means they may be readily connected to the sections 7 of the sucker rod, but it will of course be understood that this member 8 may be connected with the section 7 of the rod 6 in any convenient manner. These members 8 may be used to connect each adjacent section 7 of the rod 6, or, if desired, they may be distributed at a greater distance from each other. The member 8, which is round in `cross section, has flattened surfaces 11 by which it may be conveniently turned or held with the wrench.

Projecting' from the member 8 there is a plurality of ears 12, having openings 13, and wings 14 each having two lugs 15, which are disposed one at' each side of the ears 12, there being openings 16 in the lugs 15 which register with the openings 13 so that the pins 17, which are disposed through the openings 13 and 16, will hold the lifting wings 14 pivoted, and in position. Each of the lifting wings 14 has a depending heel 18, which normally rests in the recesses 19 in the member 8. The wings 14 are constructed and are so disposed that their' sides 20 and 21 extend radially, the bottom of the sides 20 being beveled at 23, as appears in Fig. 4 of the drawings, and also as shown by the do-tted lines in Fig. 3 of the drawings. Beveled extensions 24 are integral with the wings 14, and extend from the sides 21 0f the said wings, the upper surfaces of the extensions 24 being beveled and the width of the said extensions 24 decreasing outwardly. The bevels on the upper surfaces of the extensions 24 are clearly shown in Figs. 4 and 5 of the drawings. Each pair of lugs 15 is united at 25 at the top of the wings 14, and this portion 25 extends to the periphery of the wings, and is beveled at 26, the portion 25 of the lugs 14 reinforcing the wings and the beveled portions 26 serving to prevent the wings from catching against any small particles which may project in the inner sides of the tubing, and' also serving to prevent the wings from catching on the joints on the tubing when the rod is operated.

It will be seen that the wings may be moved upwardly relatively to the body member 8, and that in this upward position the wings will be disposed close to the body member S, so that the wings will be supported on the down stroke and the strain will be taken off the rivets. The wings overlap as has been described, whereby. a perfectly reinforced joint is made between the wings, when the rod is raised. The movement of the wings 14C relatively to the casing 5 will prevent the rod 6 from buckling or breaking, since the movement of.

the wings lil against the casing 5 will prevent any material bend in the rod 6. Be-

cause of the infrequent number of blow.

the sucker rod may be disposed in a tubev which is lowered in the casing.

It should be stated that the usual type of pump will be used with the device set forth in this application, and this usual type of pump will be disposed at the botom of the well. The wings 14 will be used at the various joints on the sucker rod 6, which is connected with this pump, and these wings 14 will be spaced apart all the way up the sucker rod. In action the oil well pump now in use is continuously sanding up and the plunger cuts out rapidly, and it is then impossible to use the well until all the tubing rods can be pulled out of the well, and the pump cleaned and repaired. "With this attachment the sand is removed by` keeping it in suspension in the well, or thoroughly stirring it up in equal density from the bottom to the top of the well. My improvement will also assist quite materially in relieving the weight of a full column ofV oil back against the pump. It is` this immense weight that causes the pump to blow through or blow out. strain on the suction rod will ized.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

In a device of the character described, a pump rod, a plurality of lifting wings having radially extending sides, one set of sides having bevels which increase in width inwardly, and beveled extensions onthe other set of sides for engaging the first-mentioned bevels, the beveled extensions increasing in width inwardly.
